The Long Surname DNA Project
Including Longe, Lang and Other Variations
A Family Tree DNA Surname Project

Project Objective: The objective of the Long Surname DNA Project is to enable Longs to expand and refine their family trees using genetic information to identify the progenitors of the Long families and their geographical origins and migration paths.
For Longs having well-documented family histories going back five or more generations, financial assistance may be available...contact the administrator.
The Long surname frequency ranks 86th in the USA
and 189th in the UK. (source:
It ranks 13th in Cambridgeshire.
Here's how Y-DNA testing works: Every male has a single Y chromosome that is inherited from his natural father. Thus, all men in a father-to-son paternal line have an identical Y chromosome (except for random mutations that occur on the average of every 500 generations). Laboratories can analyze the Y chromosome by counting markers at specific locations. This results in a sequence of numbers called a "haplotype." If two men are found to have identical or very similar haplotypes, it indicates that they have a common ancestor in their paternal lines. For example, a Long in Delaware is tested and found to match a Long in Texas and a Long in Ireland. These Longs can then conclude that they are all descended from a common Long ancestor. It is also possible to estimate the number of generations back to this most recent common ancestor.
In addition to Y-DNA testing, there are two other types of DNA testing used for genealogy. They are mtDNA testing and Autosomal testing. These tests can be taken by females and males. The Long Surname DNA Project is primarily intended for Longs that have taken or wish to take a Y-DNA test.

Who's Doing It! Go to our Participants Page. Search on the names of counties where your earliest known Long ancestors lived.
Eligibility: See the Join Info page.
Privacy & Security: If you or your Long relative wish to remain anonymous, no problem! Just sign up as "Anonymous Long" or choose a fictitious name. Anonymous participants will be identified by their test kit number. Participants, whether anonymous or not, can also elect to keep their haplotype information private. See the Security & Privacy page.
Cost: The regular group rate for a Y-DNA test is: $49 for the 12-marker test, $124 for the 25-marker test, $149 (~ £96.4) for the 37-marker test (recommended), $239 for the 67-marker test and $339 for the 111-marker test. Check with the Group Administrator is see if any specials are in effect.
How To Order a Test: See the Join Page
If you are a participant in the IBM/National Geographic's Genographic Project and your surname is Long, you can participant in this Long Surname DNA Project at no additional cost.
Donations Accepted. The Long Surname DNA Project is seeking contributions. Contributions are used to purchase test kits for Longs that are not interested in family history and/or are unwilling to be tested due to the expense. To make a secure donation using a credit card, go to http://www.familytreedna.com/group-general-fund-contribution.aspx
Test Results: Test results can be accessed from the FTDNA Long Page which displays buttons that you can click on to get the specific Y-DNA or mitochondrial DNA marker values associated with each kit number. It may take several minutes for the data to appear. No actual discussion of results is provided. (Such discussions are typically carried-on between individual group participants having matching results.)
